I can see that logging_filter.rb is located in my /var/canvas/lib directory and this file was not part of the update (modification date still says 15FEB), so it looks like I've somehow lost my environment information. I went back through the production start instructions and noticed that the compile_assets command was used a little differently:

RAILS_ENV=production bundle exec rake canvas:compile_assets

I tried running the command this way, but got the same error message. Prior to running the initial compile_assets command, during the "Upgrade and Install Bundled Gems" section, I was prompted to update rails:

So, it looks like the update and install of the bundled gems worked. However, Ruby doesn't seem to know where the /var/canvas/lib directory is anymore. Of course, I'm new to Canvas and I don't know much about Ruby & Bundler, so I'm hoping that someone can help me figure out how to resolve this dependency issue.

Kurt, since you've referred to a "Canvas upgrade" (something that cloud folks don't have to worry about) I am going to guess that you are self-hosting Canvas, so I've shared your question with the Canvas Developers group.

We are giving the Canvas Admins area a little bit of love (especially questions that are really, really old) and just want to check in with you. This will also bring this question new attention.
